Suppose f(x) = mx + b. What is the inverse function in terms of m and b?

katrin2010 [14]

Answer:

f^(-1)(x) = (x-b)/m or x/m - b/m

Step-by-step explanation:

f(x) = y = mx + b

To find the inverse function, interchange x and y and solve for y, i.e.

x = my + b

my = x-b

y = (x-b)/m = x/m - b/m

AC if TC = 20q + 10q^2?

Alexus [3.1K]

Answer:

AC = (20+ 10q)

Step-by-step explanation:

Given that,

Total cost, TC = 20q + 10q²

We need to find AC i.e. average cost.

It can be solved as follows :

$AC=\dfrac{TC}{q}\\\\AC=\dfrac{20q + 10q^2}{q}\\\\AC=\dfrac{q(20+ 10q)}{q}\\\\AC={(20+ 10q)}$

So, the value of AC is (20+ 10q).

Write an equation parallel to y= -5/2x + 9 that passes through the point (-6,7) brainly

frozen [14]

Answer:

Step-by-step explanation:

If two lines are parallel, that means their slopes are equal.

And we also know that the line must pass through (-6,7)

And with our point-slope equation, we get the equation:

$y-7 = -\frac{5}{2} (x+6)$

$y - 7 = -\frac{5}{2} x-15\\y= -\frac{5}{2} x-8$ <------ Answer

Hope that helps!
